Generating visual data stories

ABSTRACT

This disclosure describes one or more embodiments of systems, non-transitory computer-readable media, and methods that intelligently and automatically analyze input data and generate visual data stories depicting graphical visualizations from data insights determined from the input data. For example, the disclosed systems automatically extract data insights utilizing an in-depth statistical analysis of dataset groups from data-attribute categories within the input data. Based on the data insights, the disclosed systems can automatically generate exportable visual data stories to visualize the data insights, provide textual or audio-based natural language summaries of the data insights, and animate such data insights in videos. In some embodiments, the disclosed systems generate a visual-data-story graph comprising nodes representing visual data stories and edges representing similarities between the visual data stories. Based on the visual-data-story graph, the disclosed systems can select a relevant visual data story to display on a graphical user interface.

BACKGROUND

In recent years, analysts and engineers have developed data analysissystems to collect and analyze large amounts of raw data as part ofdetecting data trends or developing a graphical narrative. Inparticular, some data analysis systems can collect and summarize rawdata. For example, some conventional automated data analysis systemsattempt to identify statistics to simplify the process of creatingnarrative reports from large amounts of raw data but suffer from severaltechnical shortcomings. In particular, conventional systems often failto accurately identify data trends within time series or other datasets,misidentify relationships among complex datasets, and cannot presentdata insights as part of a snapshot of larger trends within inputdatasets.

As just suggested, some conventional automated data analysis systemsfail to accurately generate narratives with meaningful insights from alarge number of insights. In some cases, the number insights derivedfrom a dataset can be large or seemingly infinite. Indeed, datasets caninclude multiple data fields, and data insights can be created fromvarious combinations of the data fields and values corresponding to thedata fields. For example, a data insight can include a statisticalcalculation derived from particular data fields and values. Due to thelarge number of such insights, many conventional systems cannotaccurately focus on salient insights for creating a narrative graphic orreport. In addition, such conventional systems inefficiently utilizecomputing resources by (i) generating an inordinate number of extractedinsights for analysts to search through in a time consuming and tediousprocess and by (ii) inaccurately selecting uninteresting or irrelevantinsights to generate as part of a narrative report.

Furthermore, many conventional systems fail to identify semanticrelationships between a collection of data insights. Consequently, manyconventional systems cannot identify relevant insights (or resultingdata narratives) that show relationships between different types of datawithin a dataset and surface the same (or irrelevant) insights. Becauseof the limits of conventional systems, data analysts often manuallyreview and search from insights not identified by conventional automateddata analysis systems to create data narrative reports. Oftentimes,creating such narrative reports in this manner from a large collectionof derived insights is time consuming and impractical. Moreover, in manycases, creating data narrative reports in this manner also results in anexcessive number of steps executed by the computing devices of dataanalysts—at the expense of additional computing resources.

In addition to an excessive number of computing steps, conventionalsystems often cannot integrate multiple applications and tools to createnarrative reports from insights found from raw input data. For instance,conventional systems often generate an excessive list of data insightsthat data analysts selectively transfer to a separate report-creationtool to construct presentable data narrative reports. Indeed, in manycases, conventional systems cannot integrate or automate multiple toolsand thus require data analysts to perform a number steps to manuallyselect data insights and to create data narrative reports using separatecreation and/or editing tools for such reports.

In addition to failed integration and automation, many conventionalsystems also determine cursory insights that fail to provide a holisticunderstanding of the information present within the raw input data. Forinstance, conventional systems often primarily focus on enumerating (andanalyzing) combinations of different data fields (e.g., data of a firstheader compared to data of a second header) from input data tables togenerate insights. As an example, conventional systems often simplygenerate insights that calculate statistical facts (e.g., a mean)between values of different data fields (e.g., between headers) in lieuof providing in-depth insights that identify unique and meaningfulanalyses of the raw input data.

SUMMARY

This disclosure describes embodiments of systems, non-transitorycomputer-readable media, and methods that solve one or more of theforegoing problems. For instance, the disclosed systems intelligentlyand automatically analyze input data and generate visual data storiesdepicting graphical visualizations from data insights determined fromthe input data. As suggested, the disclosed systems can automaticallyextract data insights utilizing an in-depth statistical analysis ofdataset groups from data-attribute categories within the input data.Based on the data insights, the disclosed systems can automaticallygenerate exportable visual data stories to visualize the data insights,provide textual or audio-based natural language summaries of the datainsights, and animate such data insights in videos. Such a visual datastory may, for instance, include graphs and natural language summariescomparing particular groups within the larger dataset, such as visualdata stories comparing data trends between countries (or other datagroups) in time-series data for viral infections, stock-index values, orvarious other raw-data counts.

In addition to generating visual data stories, the disclosed systems canselect a relevant visual data story to display on a client device. Insome cases, for instance, the disclosed systems generate avisual-data-story graph comprising nodes representing visual datastories and edges representing similarities (and/or differences) betweenthe visual data stories. Based on the visual-data-story graph, in someinstances, the disclosed systems select a relevant visual data story todisplay on a graphical user interface. Such a graphical user interfacecan support browsing or provide similar (or dissimilar) visual datastories in relation to the selected visual data story. By generating andselecting relevant visual data stories, in many instances, the disclosedsystems provide a computationally-guided process of automaticallygenerating presentable and coherent visual data stories with in-depthdata insights from complex, raw input data.

DETAILED DESCRIPTION

This disclosure describes embodiments of a visual-data-story system thatgenerates visual data stories comprising graphical visualizations andnatural language summaries of data insights determined from raw inputdata. For instance, the visual-data-story system compares data-attributevalues corresponding to dataset groups (e.g., countries, demographicpopulations, organizations) from data-attribute categories in a dataset(e.g., raw input data). Based on such a comparison, thevisual-data-story system determines data insights across differentdataset groups and generates visual data stories that both graphicallyvisualize and summarize the data insights comparing different datasetgroups. Having such visual data stories, the visual-data-story systemgenerates a visual-data-story graph that includes nodes for the visualdata stories and edges to represent similarity distances betweendata-story properties of visual-data-story pairs from the visual datastories. Upon selecting a relevant visual data story based on thesimilarity distances within the visual-data-story graph, thevisual-data-story system displays, within a graphical user interface,the selected visual data story and/or a selectable option for a similarvisual-data story in relation to the selected visual data story.

As just mentioned, in one or more embodiments, the visual-data-storysystem determines data insights from input data to generate visual datastories. In particular, in some embodiments, the visual-data-storysystem receives raw input data (e.g., tabular data) having one or moredata-attribute categories (e.g., tabular headers). In certain instances,the visual-data-story system analyzes (e.g., using statistical analysesand/or modelling) data-attribute values (e.g., cell values from tabulardata) to determine data insights. For example, the visual-data storysystem determines data insights across different dataset groupsutilizing a statistical analysis that compares data-attribute valuescorresponding to the dataset groups. In some embodiments, thevisual-data-story system analyzes dataset groups within data-attributecategories to determine data insights of one or more dataset groups(e.g., a grouping of data-attribute values in relation to a commondata-attribute value within a data-attribute category).

In one or more embodiments, the visual-data-story system utilizesdata-attribute values from one or more dataset groups to determine datainsights, such as data trends, energy ratios, and/or data distributionsfrom the data-attribute values. As an example, the visual-data-storysystem utilizes a linear least-squares regression and/or a slidingtime-window with data-attribute values of a dataset group in a timeseries to determine a data-trend insight. To illustrate, thevisual-data-story system determines detected trends for a dataset groupor a time-series analysis of the dataset group, such as increases ordecreases in viral infections or stock-index values in particularcountries across time.

Based on such data insights, in some embodiments, the visual-data-storysystem generates a visual data story. For instance, in one or moreinstances, the visual-data-story system utilizes a predefined templatehaving certain data story properties (e.g., data-attribute categoryname, data-attribute values, one or more dataset group names, one ormore dataset group insights, and/or data insight comparisons) toorganize (or utilize) determined data insights into meaningful visualdata stories. Furthermore, in some cases, the visual-data-story systemgenerates the visual data story to visually represent the determineddata insights and comparisons of the data insights. For example, thevisual-data-story system visually represents determined data insights ina visual data story using visual charts and/or video animations toindicate the data insights. In addition to such graphics, in certaininstances, the visual-data-story system also generates text-based and/oraudio-based natural language summaries for the determined data insightsas part of the visual data story.

Having generated multiple visual data stories comparing different datagroups, the visual-data-story system can also generate avisual-data-story graph. For instance, in one or more embodiments, thevisual-data-story system generates a visual-data-story graphrepresenting the visual data stories and their relationships to othervisual data stories. In particular, in one or more instances, thevisual-data-story system determines similarity distances betweendata-story properties of visual-data-story pairs from the generatedvisual data stories. Then, the visual-data-story system generates nodesto represent the visual data stories and edges between the nodes torepresent the similarity distances (or similarity scores calculated fromthe similarity distances). Furthermore, in some cases, thevisual-data-story system selects visual data stories from thevisual-data-story graph to provide selectable recommendations of similarand/or dissimilar visual data stories within a graphical user interfacein relation to a displayed (or selected) visual data story.

Such a graphical user interface provides a tool to explore and customizefor presentation visual data stories selected by—or determined similar(or dissimilar) to visual data stories selected by—the visual-data-storysystem. For instance, in some embodiments, the visual-data-story systemprovides, for display within a graphical user interface, a visual datastory having one or more visual elements (e.g., a visualized and/oranimated chart), text summaries, selectable options for audio summaries,and/or other selectable options for interactions with the visual datastory (e.g., bookmarking the visual data story). In some cases, suchvisual data stories include video animations to illustrate data insightsor to highlight given data insights from the visual data story. Inaddition, in some embodiments, the displayed graphical user interfacealso includes selectable options to bookmark one or more visual datastories to combine (or stitch together) the visual data stories into acoherent visual data story (e.g., a stitched-visual-data story) thatpresents one or more data insights from the raw input data.

The disclosed visual-data-story system provides a number of advantagesover conventional automated data analysis systems. As mentioned above,conventional systems fail to accurately generate narratives withaccurate data insights and instead require time consuming and tediousreview by data analysts to generate meaningful narratives from raw inputdata. Unlike conventional systems, the visual-data-story systemefficiently and intelligently automates a process of generating relevantvisual data stories—by starting with simple input data and outputtingselect visual data stories. For example, in contrast to thepainstaking-review processes of conventional systems, thevisual-data-story system generates and selects for display a relevantvisual data story by determining similarity distances between visualdata stories and generating a visual-data-story graph that guidesselection. Additionally, unlike conventional systems that require timeconsuming insight searches, the visual-data-story system sometimesdetermines relationships between the visual data stories using such avisual-data-story graph and also makes the full generated set of visualdata stories easily searchable and/or identifiable. Accordingly, in manyinstances, the visual-data-story system automates the process ofgenerating relevant visual data stories (e.g., from simple input data togenerating reports that include visual data stories) to reduce thecomputational resources and time needed to generate such meaningful datastories.

In addition to intelligently automating a process for generating visualdata stories, the visual-data-story system generates graphical userinterfaces that increase the efficiency and ease of quickly reviewing,searching through, and selecting visual data stories. For instance, byproviding, for display within a graphical user interface, a selectedvisual data story and recommended visual data stories from the visualvisual-data-story graph, the visual-data-story system promotes quick andeasy navigation through data stories with selectable options to selectthe visual data stories to include in a presentable medium (e.g., afinal visual data story report). As such, in one or more embodiments,the visual-data-story system creates a computationally-guided process ofautomatically generating presentable and coherent visual data storiesthat indicate in-depth data insights directly from raw input data—withfewer navigational steps and fewer specialized skills in data analysis.

Furthermore, unlike conventional approaches that require utilizingmultiple applications to generate a presentable narrative from raw data,the visual-data-story system provides an efficient, streamlined pipelinethat intakes complex, raw data and outputs presentable visual datastories within a single platform. For example, in some cases, thevisual-data-story system utilizes raw input data to generate visual datastories, provide selectable options to quickly select form the visualdata stories (e.g., bookmark), and combine (e.g., stitch) the selectedvisual data stories to generates a set of exportable visual data storiesthat present data insights via visual illustrations, text, audio (e.g.,by generating an audio file), and/or video (e.g., by generating a videofile). Indeed, in one or more embodiments, the visual-data-story systemgenerates such exportable visual data stories within a singleplatform—rather than the cumbersome approach of conventional systemsthat require opening multiple applications, transferring data betweenthe multiple applications, and maintaining consistencies/formattingrequirements between the multiple applications.

Furthermore, in one or more embodiments, the visual-data-story systemalso generates visual data stories that accurately and intelligentlyanalyze raw input data. For example, the visual-data-story systemperforms statistical analyses (and/or modelling) to determine in-depthdata insights (such as trend detection and time-series analysis) betweensubgroups (e.g., dataset groups) of each data attribute in the raw inputdata to generate more detailed data insights. By doing so, thevisual-data-story system automatically generates visual data storiesthat provide more in-depth data insights from input data compared to thecursory data insights of many conventional systems. For example, in someinstances, the visual-data-story system utilizes input datasets todetermine detailed data insights (e.g., between subgroups), such as “inthe U.S., the number of female customer visits is 82.09% of the totalnumber of customer visits—similar to the percentage of female customervisits in Brazil” rather than only determining a data insight indicatingthat “the number of female customer visits is 80.09% of the total numberof customer visits.”

Indeed, in many instances, the visual-data-story system introduces anunconventional approach to generate visual data stories from raw inputdata. For instance, in some embodiments, the visual-data-story systemutilizes an unconventional ordered combination of actions to extractin-depth data insights from input data, generate visual data stories forthe data insights, and provide relevant visual data stories using agenerated visual-data-story graph to generate a meaningful and coherentvisual data story from raw input data. In other words, thevisual-data-story system introduces a process for generating visual datastories from raw input data that is not utilized by conventionalsystems. By utilizing a virtually infinite (or excessively large)collection of data insights from the raw input data and avisual-data-story graph for the data insights, the visual-data-storysystem generates visual data stories that could not be practicallydetermined by humans.

Turning now to the figures, FIG. 1 illustrates a schematic diagram ofone embodiment of a system 100 (or environment) in which avisual-data-story system 106 operates in accordance with one or moreembodiments. As illustrated in FIG. 1, the system 100 includes serverdevice(s) 102, a network 108, and a client device 110. As furtherillustrated in FIG. 1, the server device(s) 102 and the client device110 communicate via the network 108.

As shown in FIG. 1, the server device(s) 102 include a data analyticssystem 104 which further includes the visual-data-story system 106. Forinstance, the server device(s) 102 includes, but is not limited to, acomputing (or computer) device (as explained below with reference toFIG. 13). In some embodiments, the visual-data-story system 106 receives(or identifies) raw input data and determines one or more data insightsfrom the data. Based on the data insights, in some embodiments, thevisual-data-story system 106 generates visual data stories and selects arelevant visual data story for display using a story graph from thevisual data stories, as described above and further below.

As also shown in FIG. 1, the system 100 includes the client device 110.In one or more embodiments, the client device 110 includes, but is notlimited to, a mobile device (e.g., smartphone, tablet), a laptop, adesktop, or any other type of computing device, including thoseexplained below with reference to FIG. 13. In some instances, althoughnot shown in FIG. 1, the client device 110 is operated by a user toperform a variety of functions (e.g., via a digital content application112). For example, the client device 110 performs functions such as, butnot limited to, inputting raw data, requesting visual data stories,interacting with visual data stories, and/or selecting visual datastories (e.g., for stitching). In one or more embodiments, the clientdevice 110 receives and displays visual data stories (and various otherelements) from the visual-data-story system 106. Furthermore, as shownin FIG. 1, the client device 110 communicates with the server device(s)102 via the network 108.

To access the functionalities of the visual-data-story system 106 (asdescribed above), in certain embodiments, a user interacts with thedigital content application 112 on the client device 110. For example,the digital content application 112 includes one or more softwareapplications (e.g., to display, utilize, or interact with visual datastories and input data in accordance with one or more embodimentsherein) installed on the client device 110. In some instances, thedigital content application 112 is hosted on the server device(s) 102.In addition, when hosted on the server device(s), the digital contentapplication 112 is accessed by the client device 110 through a webbrowser and/or another online interfacing platform and/or tool.

Although FIG. 1 illustrates the visual-data-story system 106 beingimplemented by a particular component and/or device within the system100 (e.g., the server device(s) 102), in some embodiments, thevisual-data-story system 106 is implemented, in whole or part, by othercomputing devices and/or components in the system 100. For instance, insome embodiments, the visual-data-story system 106 is implemented on theclient device 110. In particular, in some embodiments, the client device110 generates the visual data stories in accordance with one or moreembodiments.

Additionally, as shown in FIG. 1, the system 100 includes the network108. As mentioned above, in some instances, the network 108 enablescommunication between components of the system 100. In certainembodiments, the network 108 includes a suitable network and maycommunicate using any communication platforms and technologies suitablefor transporting data and/or communication signals, examples of whichare described with reference to FIG. 13. Furthermore, although FIG. 1illustrates the server device(s) 102 and the client devices 110communicating via the network 108, in certain embodiments, the variouscomponents of the system 100 communicate and/or interact via othermethods (e.g., the server device(s) 102 and the client device 110communicating directly).

As mentioned above, in one or more embodiments, the visual-data-storysystem 106 provides a computationally-guided process of automaticallygenerating presentable and coherent visual data stories that indicatedata insights directly from input data. For example, FIG. 2 illustratesthe visual-data-story system 106 determining data insights, generatingvisual data stories and visual-data-story graphs, and displaying visualdata stories and recommendations for visual data stories utilizing acomputationally-guided process.

As shown in FIG. 2, the visual-data-story system 106 receives an inputdataset 202. Then, as illustrated in FIG. 2, the visual-data-storysystem 106 determines data insights in an act 204 from thedata-attribute values of the input dataset 202 by detecting attributesand dataset groups and extracting data insights for the attributes anddataset groups. Subsequently, the visual-data-story system 106 utilizesthe determined data insights to generate visual data stories in an act206 by organizing data insights and generating visual data stories. Asfurther shown in FIG. 2, the visual-data-story system 106 selects visualdata stories in an act 208. Indeed, as also shown in FIG. 2, thevisual-data-story system 106 generates a visual data story 210 invarious formats within a graphical user interface from one or morevisual data stories.

As just mentioned, the visual-data-story system 106 receives (oridentifies) an input dataset (e.g., as shown in FIG. 2). In one or moreembodiments, the visual-data-story system 106 receives an input datasetas a file upload from a client device (e.g., client device 110). In someinstances, the visual-data-story system 106 receives (or identifies) adataset from a stored file. In one or more embodiments, a datasetincludes a collection of values. In some instances, a dataset includes acollection of values that are organized according to data-attributecategories.

In particular, in some embodiments, a dataset includes a collection oftabular data having data values (e.g., data-attribute values) that areorganized according to data-attribute categories to form tables havingcolumn and/or row headers and data values corresponding to the columnand/or row headers In some cases, a dataset can include tabular datathat is also recorded (or organized) over a time period. For instance, adataset can include, but is not limited to, a spreadsheet file (e.g.,.xls file, .numbers file, .gsheet file), text files organized usingnotations and/or symbols (e.g., a CSV file, TSV file, DSV file, JSONfile), and/or a database file (e.g., .sqlite file, .sql file). Inaddition, in one or more embodiments, data-attribute values include datavalues within cells, columns, and/or rows of a dataset (e.g., variouscombinations of textual and/or numerical values within a dataset).

As indicated above, in one or more embodiments, the data values of adataset are organized according to data-attribute categories. In someembodiments, a data-attribute category includes a label or otherindicator that categorizes a set of data values to a given concept,object, place, and/or person. For example, a data-attribute categorysometimes includes a header within tabular data. Furthermore, a datasetgroup sometimes includes a collection of data-attribute values from oneor more data-attribute categories that are associated with a specificdata-attribute value of a given data-attribute category.

To illustrate, in one or more embodiments, a dataset includes tabulardata that includes data-attribute categories, such as countries, cities,and daily COVID-19 cases. Each of the data-attribute categories (e.g.,countries, cities, and daily COVID-19 cases) include data-attributevalues. For example, the data-attribute category of countries hasdata-attribute values of U.S.A., Brazil, China, India, Australia, andItaly (as cell values). In addition, as an example, a dataset group forthe data-attribute value of U.S.A. (from the countries data-attributecategory) includes the cities and daily COVID-19 case data-attributevalues that correspond to the data-attribute value of U.S.A.

As further shown in the act 204 of FIG. 2, the visual-data-story system106 determines data insights from an input dataset. In particular, inone or more embodiments, the visual-data-story system 106 detectsdata-attribute categories within an input dataset and dataset groups aspart of the data-attribute categories. Indeed, dataset groups (e.g.,countries, cities, demographic groups, vehicle manufacturer) arespecific examples of data-attribute categories. In one or moreembodiments, the visual-data-story system 106 extracts (or derives) datainsights from the data-attribute values in the dataset by comparingdata-attribute values that correspond to dataset groups or otherdata-attribute categories. For example, the visual-data-story system 106utilizes statistical analyses and/or modelling to detect trends ortime-series interpretations from attribute-data values belonging to adata-attribute category (e.g., a dataset group). The visual-data-storysystem 106 determining one or more data insights from an input datasetis described in greater detail below (e.g., in relation to FIGS. 3 and4).

In one or more embodiments, a data insight includes information thatprovides an interpretation and/or understanding from an analyticaland/or statistical assessment of data from a dataset. For example, adata insight includes detected trends in a time series and/or timeseries analysis that include statistical evaluations (e.g., means,medians, modes, data extremums, data minimums), data distributions fromthe dataset, and/or detected significant data value changes. In one ormore embodiments, the visual-data-story system 106 determines datainsights as numerical values, a set of values that correspond to a trendor significant distribution, and/or as flags that indicate particularevents (e.g., significant data value changes, trend changes).

In some instances, as shown in the act 204 of FIG. 2, thevisual-data-story system 106 visualizes determined data insights. Forexample, the visual-data-story system 106 visualizes a determined datainsight as a visual data story (e.g., a visual data story piece) thatincludes a graphical visualization and natural language summaryspecifically for the determined data insight. To illustrate, as shown inFIG. 2, the visual-data-story system 106 visualizes a data insight as avisual data story 205.

As further shown in the act 206 of FIG. 2, the visual-data-story system106 generates visual data stories. In one or more embodiments, thevisual-data-story system 106 utilizes one or more detected data insightsto generate visual data stories. For instance, the visual-data-storysystem 106 utilizes a predefined template having certain data storyproperties (e.g., data-attribute category name, data-attribute values,one or more dataset group names, one or more dataset group insights,and/or data insight comparisons) to visualize data insights withinvisual data stories. Moreover, in one or more embodiments, thevisual-data-story system 106 generates a visual data story from asingular determined data insight and/or multiple data insights. Toillustrate, as shown in FIG. 2, the visual-data-story system 106generates a visual data story 207 that provides a graphicalvisualization and/or natural language summary of a comparison betweendetermined data insights for multiple dataset groups (e.g., Group A vs.Group B). The visual-data-story system 106 generating visual datastories from data insights is described in greater detail below (e.g.,in relation to FIGS. 3, 4, and 6).

In some embodiments, a visual data story includes a graphicalvisualization of a data insight. For instance, a visual data storyincludes various combinations of graphical elements (e.g., charts,graphs, bars), text, and audio to illustrate a data insight determinedfrom a dataset. In some instances, a visual data story includes anatural language summary (e.g., text and/or audio-based) generated froma data insight. In particular, in one or more embodiments, thevisual-data-story system 106 generates a visual data story that displaysvisual charts from data insights to compare the data insights while alsoproviding text- and/or audio-based summaries for the compared datainsights.

As further shown in the act 208 of FIG. 2, the visual-data-story system106 selects visual data stories based on visual-data-storyrelationships. In particular, in some cases, the visual-data-storysystem 106 determines visual-data-story relationships by generating avisual-data-story graph representing similarities or dissimilaritiesbetween visual data stories. Indeed, in some embodiments, thevisual-data-story system 106 utilizes the similarity or dissimilarityrelationships between visual data stories to select visual data storiesto surface within a graphical user interface (e.g., as recommendedvisual data stories). The visual-data-story system 106 generating andutilizing a visual-data-story graph is described in greater detail below(e.g., in relation to FIG. 5).

In one or more embodiments, a visual-data-story graph includes acollection of nodes and edges that represent visual data stories andrelationships between the visual data stories. For instance, avisual-data-story graph represents visual data stories as nodes andsimilarity distances between data-story properties of visual-data-storypairs from the visual data stories as the edges that connect the nodes.Indeed, in one or more embodiments, a visual-data-story graph incudesnodes representing the available auto-generated visual data stories anda set of edges that represent all positive pairwise similarities (e.g.,via similarity distances) between the visual-data-story pairs.

As also shown in FIG. 2, the visual-data-story system 106 selects visualdata stories in the act 208 by receiving visual data story selectionsfrom a client device and combining selected visual data stories togenerate a larger (or final) visual data story for the input dataset202. For example, the visual-data-story system 106 provides visual datastories from the visual-data-story graph as selectable visual datastories (e.g., as recommendations) in a graphical user interface of aclient device. In some instances, the visual-data-story system 106identifies a user interaction with a selectable visual data story or aselection option corresponding to the visual data story (e.g., abookmark selection button) as a received selection of the visual datastory. Then, in some instances, the visual-data-story system 106combines (stitches) the selected (or bookmarked) visual data stories toform (or generate) a larger visual data story that represents theselected visual data stories in a singular stitched-visual-data story(or report). The visual-data-story system 106 combining selected visualdata stories to generate a larger visual data story is described ingreater detail below (e.g., in relation to FIG. 6).

In some instances, as shown in FIG. 2, the visual-data-story system 106receives user settings 212 from a user. For example, in one or moreembodiments, the visual-data-story system 106 receives user settings todetermine parameters for data insight determinations. For example, thevisual-data-story system 106 receives a threshold percentage fordetermining trend insights (e.g., as described below in relation to FIG.4) and/or a percentage a of a range of the distribution (e.g., asdescribed below in relation to function (2)). Furthermore, in one ormore embodiments, the visual-data-story system 106 also receives athreshold distance and/or threshold similarity score (e.g., as describedbelow in relation to functions (3)-(10)) as a user setting.

In one or more embodiments, the visual-data-story system 106 receivesuser settings that indicate a filter. In particular, in someembodiments, the visual-data-story system 106 receives filter values tofilter a visual-data-story graph (for recommended visual data stories).As an example, in one or more embodiments, the visual-data-story system106 receives a filter value for a data-attribute value. Then, in someinstances, the visual-data-story system 106 filters thevisual-data-story graph to include visual data stories that include thefilter value for the data-attribute value. For example, if the filtervalue indicates to focus on dataset groups having the data-attributevalue of “U.S.,” the visual-data-story system 106 filters thevisual-data-story graph (or visual-data-story space) to only includevisual data stories that include “U.S.” as a dataset group.

As an example, the visual-data-story system 106 can generateinfographics with data charts from a dataset without a user havingtechnical knowledge in data analysis. To illustrate, thevisual-data-story system 106 receives a dataset for COVID-19 cases invarious countries and globally from a user that desires to create apresentable data story from the raw dataset. Upon receiving the dataset,in one or more embodiments, the visual-data-story system 106automatically generates a number of visual data stories comparingCOVID-19 infection cases in different locations from the dataset anddisplays, within a graphical user interface, a visual data storycomparing the COVID-19 cases between Global and the U.S. (e.g., on adata story user interface panel) and also displays recommended visualdata stories (e.g., on a data story recommendation user interfacepanel).

In addition to displaying a selected visual data story selected by thevisual-data-story system 106, in some embodiments, the visual-data-storysystem 106 receives an indication of a user interaction with aselectable option to select the visual data story comparing the COVID-19situation between Global and the U.S. Furthermore, in one or moreembodiments, the visual-data-story system 106 receives an indication ofa user interaction with selectable options to select visual data storiesfrom the recommended visual data stories (e.g., on the data storyrecommendation user interface panel) that have a similar increasing datatrend as the Global vs. the U.S. visual data story (e.g., a Global vs.Brazil visual data story having an increasing trend). Likewise, in someinstances, the visual-data-story system 106 also receives an indicationof a user interaction with selectable options to select visual datastories from the recommended visual data stories that have a dissimilar(decreasing) trend to that of the Global vs. the U.S. visual data story(e.g., a Global vs. Australia visual data story having a decreasingtrend).

Upon receiving the selected visual data stories, in one or moreembodiments, the visual-data-story system 106 receives an indication ofa user interaction with a selectable option to combine the selectedvisual data stories. As a result, in one or more embodiments, thevisual-data-story system 106 combines (or stitches) the selected visualdata stories into a larger coherent visual data story (e.g., as areport) that includes the similar and dissimilar selected visual datastories in accordance with one or more embodiments. By doing so, in oneor more embodiments, the visual-data-story system 106 quickly andautomatically presents data insight patterns and generates meaningfulvisual data stories within a short amount of time compared toconventional approaches.

As mentioned above, in one or more embodiments, the visual-data-storysystem 106 generates a visual data story. For example, FIG. 3illustrates a visual data story 306 that is automatically generated bythe visual-data-story system 106 from an input dataset 302. As shown inFIG. 3, the visual-data-story system 106 receives the input dataset 302through a file upload user interface 304. Then, as shown in FIG. 3, thevisual-data-story system 106 utilizes the input dataset 302 to generateand provide, for display within a graphical user interface 305, thevisual data story 306.

As shown in FIG. 3, the visual-data-story system 106 generates thevisual data story 306 having a graphical visualization (e.g., a trendchart) from a data insight determined from the input dataset 302. Inparticular, in FIG. 3, the visual data story 306 illustrates the datainsight from a comparison of the COVID-19 situation between Global andthe U.S. from the input dataset 302. Indeed, as shown in FIG. 3, thevisual-data-story system 106 automatically generates a chart (as avisual data story) to compare the number of COVID-19 cases between theU.S.A. vs Globally in a time series.

Additionally, as shown in FIG. 3, the visual-data-story system 106 alsoprovides, for display within the graphical user interface 305, atext-based natural language summary 308 of the data insight within thevisual data story 306. As shown in FIG. 3, the text-based naturallanguage summary 308 is automatically generated to describe the datainsight illustrated in the graphical visualization of the visual datastory 306. Moreover, as illustrated in FIG. 3, the visual-data-storysystem 106 also provides, for display within the graphical userinterface 305, a selectable option 310 to play an audio-based naturallanguage summary (e.g., a text to speech audio recording of thetext-based natural language summary 308.

As also shown in FIG. 3, the visual-data-story system 106 also provides,for display within the graphical user interface 305, a selectable option312 to play a video animation of the visual data story. In particular,in one or more embodiments, the video animation generated by thevisual-data-story system 106 displays an illustration of the datainsight and indicates, within the visual-visual-data-story graphicalvisualization, the one or more data insights described within thetext-based natural language summary 308. Additionally, as shown in FIG.3, the visual-data-story system 106 provides, for display within thegraphical user interface 305, a selectable option 314 to bookmark (orselect) the visual data story 306 (e.g., to generate a larger visualdata story and/or to save the visual data story).

To generate visual data stories, in one or more embodiments, thevisual-data-story system 106 first determines data insights from inputdata. For example, FIG. 4 illustrates the visual-data-story system 106generating a visual data story from various data insight determinationsand a data story template. As shown in FIG. 4, the visual-data-storysystem 106 determines data insight(s) in act 404 for various datasetgroups from an input dataset 402. Upon determining data insight(s) inthe act 404, the visual-data-story system 106 utilizes the datainsight(s) with a data story template 408 having data story propertiesto structure a data story. Indeed, as illustrated in FIG. 4, thevisual-data-story system 106 utilizes the determined data insight(s)from the act 404 with the data story template 408 to generate a visualdata story 412.

As an example, in reference to FIG. 4, the visual-data-story system 106identifies a dataset group (U.S.A.) and a dataset group (Global) (e.g.,a summation of each dataset groups) from the “Country” data-attributecategory in the input dataset 402. Then, the visual-data-story system106 determines an increasing trend (e.g., the linear data trend 406 c)for the dataset group (U.S.A.). In addition, in reference to FIG. 4, thevisual-data-story system 106 also determines an increasing trend (e.g.,the linear data trend 406 c) for the dataset group (Global).

Subsequently, as shown in FIG. 4 and as an example, thevisual-data-story system 106 utilizes the determined increasing trend(from the act 404) for the dataset group (U.S.A.) and a dataset group(Global) with the data story template 408 to generate the visual datastory 412. Indeed, as illustrated in FIG. 4, the visual-data-storysystem 106 structures determined data insights (e.g., the determinedincreasing trend) by using the data story properties within the datastory template 408 to generate a graphical visualization (e.g., chartsand/or video animations) and natural language summary for the visualdata story 412.

To continue the example, as shown in FIG. 4, the visual-data-storysystem 106 generates the visual data story 412 by extracting thedata-attribute category name 410 a (e.g., “Country”), data-attributevalues 410 b (e.g., the data cell values from the data-attributecategories of Country and each individual day), dataset group name 410 c(e.g., the subgroup of “U.S.A.” and “Global”), dataset group insights410 d (e.g., the increasing trend determined for the subgroup of U.S.A.and for the subgroup of Global), insight comparisons 410 e (e.g.,similarities and differences between the dataset group insights), and astory name 410 f. As indicated in FIG. 4, the story name 410 f is acombination of the subgroup categorical data values (i.e., dataset groupname) with a descriptor for the data-attribute values considered (e.g.,COVID-19 cases) to generate the name “Global vs. U.S.A. cases.” By usingthe above-mentioned data story properties within the data story template408 for the dataset groups U.S.A. and Global with the determined datainsights for the dataset groups, the visual-data-story system 106structures and generates the visual data story 412.

As mentioned above, in some instances, the visual-data-story system 106utilizes dataset groups from data-attribute categories to determine datainsights for the visual data stories by utilizing one or morestatistical analyses that compare data-attribute values corresponding toone or more dataset groups. To illustrate, in some embodiments, thevisual-data-story system 106 defines a data-attribute category as y fora set of data-attribute values

. For example, in reference to FIG. 4, the visual-data-story system 106denotes y as a data-attribute category representing “Country” (from theinput dataset 402). Then, in reference to FIG. 4, the visual-data-storysystem 106 represents the set of data-attribute values

as the set

={US, Italy, Brazil, . . . } for the data-attribute category of y.

Furthermore, in some embodiments, the visual-data-story system 106 alsodetermines data-attribute values corresponding to a dataset group as adata-attribute combination X′, which is a subset of the input dataset X(e.g., X′⊆X) as a submatrix of the dataset. Given the dataset group X′and a data-attribute category of y, the visual-data-story system 106defines the dataset group X(y_(i)=a) as the submatrix of data-attributevalues (from other data-attribute categories in the same row and/orcolumn where y_(i)=a) that correspond to a∈

(e.g., the dataset group value). To illustrate, in reference to FIG. 4,in some embodiments, the visual-data-story system 106 defines thedata-attribute category of y as “Country” and y_(i) as the “Country” ofthe ith row of the input dataset 402 (e.g., U.S.A.). Then, in one ormore instances, the visual-data-story system 106 identifies dataattribute values x_(i) (e.g., 9, 10, . . . , and 5000) as part of thedataset group X′ for the dataset group value y_(i) of “U.S.A.”

As further indicated above and shown in FIG. 4, the visual-data-storysystem 106 determines various types of data insights (in the act 404).In some instances, in accordance with the above-mentioned example of thedataset group X′, the visual-data-story system 106 denotes a time seriesx having data-attribute values x_(i) from the dataset group X′. Indeed,in one or more embodiments, the visual-data-story system 106 organizes atime series x=(x₁, x₂, . . . , x_(T)) from data-attribute values of thedataset group X′. As an example, in reference to FIG. 4, the time seriesx includes the data attribute values 9, 10, . . . , and 5000 as part ofthe dataset group X′ for the dataset group value y_(i) of “USA.”

In one or more embodiments, the visual-data-story system 106 utilizes atime series x to determine the various types of data insights (in theact 404). For example, the visual-data-story system 106 utilizes thetime series x having (x₁, x₂, . . . , x_(T)) from data-attribute valuesof the dataset group X′ to derive data values (e.g., derived data values406 a). To illustrate, in some instances, the visual-data-story system106 determines (or computes) the number of values in the time series xthat are greater than a mean value of the data-attribute values of thetime series x (e.g., derived data values 406 a). For example, thevisual-data-story system 106 derives data values that are greater than amean value of the data-attribute values x_(i) from the time series xutilizing the following function:

f(x)=|{x _(i) ∈x|x _(i)>mean(x)}|  (1)

In addition, in some instances, the visual-data-story system 106determines energy ratios (e.g., energy ratios 406 b) from portions ofparticular data-attribute values organized in a time series x for aparticular dataset group. For example, the visual-data-story system 106determines a k number of portions (or chunks) of data-attribute valuesfrom the time series x. Then, the visual-data-story system 106determines (or calculates) a sum of squares for a portion i out of the kportions (a portion of the data-attribute values). For example, todetermine the energy ratio for the portion i out of the k portions, thevisual-data-story system 106 expresses the sum of squares for theportion i as a ratio with a sum of squares over the entire time seriesx. Indeed, in one or more embodiments, the visual-data-story system 106determines energy ratios for the k portions of a time series x toutilize the energy ratios as data insights for the particular datasetgroup (e.g., as a highlighted portion).

Furthermore, in one or more embodiments, the visual-data-story system106 determines linear trends (e.g., linear data trend 406 c) as datainsights from particular data-attribute values organized in a timeseries x for a particular dataset group. For example, in someembodiments, the visual-data-story system 106 determines (or computes) alinear least-squares regression for data-attribute values of the timeseries x versus a sequence from 0 to the length of the time series xminus one. By doing so, in one or more embodiments, thevisual-data-story system 106 determines whether the data-attributevalues are increasing or decreasing across the sequence as theincreasing and/or decreasing linear trend.

In one or more instances, the visual-data-story system 106 determinestrends from particular data-attribute values organized in a time seriesx for a particular dataset group by utilizing a sliding time-window withthe time series x. More specifically, in one or more embodiments, thevisual-data-story system 106 utilizes a sliding time-window to determine(or compute) a number of data-attribute values in the slidingtime-window of the time series x that are higher or lower than a meanvalue of a previous time-window to determine an increasing and/ordecreasing trend.

For example, the visual-data-story system 106 compares a percentage ofdata-attribute values in a sliding time-window to a mean data-attributevalue of a previous time-window to a threshold percentage. When thepercentage is greater than the threshold percentage, in some cases, thevisual-data-story system 106 determines an increasing trend. Likewise,when the percentage is less than the threshold percentage, in one ormore embodiments, the visual-data-story system 106 determines adecreasing trend. In some cases, when the percentage is neither greaternor less than the threshold percentage, the visual-data-story system 106determines another distribution data insight (e.g., a symmetry test) forthe time series x.

As further shown in FIG. 4, in some embodiments, the visual-data-storysystem 106 determines (as a data insight) a data value extremum or datavalue minimum (e.g., a data value extremum/minimum 406 d) fromdata-attribute values organized in a time series x for a particulardataset group. For example, the visual-data-story system 106 identifies(or computes) the highest data-attribute value of the time series x(e.g., maximum of the time series x) as the data value extremum.Moreover, in some embodiments, the visual-data-story system 106identifies (or computes) the lowest data-attribute value of the timeseries x (e.g., a minimum of the time series x) as the data valueminimum. Indeed, in one or more embodiments, the visual-data-storysystem 106 utilizes the data value extremum/minimum from the time seriesx as a data insight.

As further indicated by FIG. 4, in some embodiments, thevisual-data-story system 106 determines (as a data insight) a datadistribution (e.g., data distributions 406 e) from data-attribute valuesorganized in a time series x for a particular dataset group. Forexample, in one or more embodiments, the visual-data-story system 106determines and utilizes a distribution of the data-attribute values of atime series x as a data insight. In some instances, thevisual-data-story system 106 further analyzes the distribution todetermine a data insight. For example, the visual-data-story system 106utilizes a symmetry test with a distribution of data-attribute valuesfrom the time series x to determine whether the distribution issymmetrical (as the data insight).

More specifically, in one or more embodiments, the visual-data-storysystem 106 utilizes a symmetry test for the time series x based on themedian of the time series x compared to a percentage α of a range of thedistribution that returns a 1 when the distribution appears symmetricand 0 if the distribution does not appear symmetric. Indeed, in one ormore embodiments, the visual-data-story system 106 utilizes a symmetrytest for the time series x in accordance with the following function:

$\begin{matrix}{{f(x)} = \{ \begin{matrix}1 & {{{if}\mspace{14mu}{{{\sum\limits_{i}x_{i}} - {{med}(x)}}}} < {\alpha( {{\max(x)} - {\min(x)}} )}} \\0 & {otherwise}\end{matrix} } & (2)\end{matrix}$

As indicated above, in some instances, the visual-data-story system 106receives a percentage α from a client device as user settings (e.g.,user settings 212). In one or more embodiments, the visual-data-storysystem 106 utilizes the determination of the symmetrical properties ofthe distribution of the time series x as a data insight.

To illustrate, in some embodiments, the visual-data-story system 106determines various data insights from an input dataset utilizing variousdata insight functions described in Table 1 below. Indeed, Table 1illustrates data insight functions utilized to determine data insights,such as derived data values, energy ratios, linear data trends, datavalue extremum/minimums, and/or data distributions.

TABLE 1 Time series Insight Functions Description f(x) = |{x_(i) ∈x|x_(i) > mean(x)}| Computes the number of data-attribute values in timeseries x that are higher than the mean of time series x Energy ratio byk portions Calculates the sum of squares of portion i out of k chunksexpressed as a ratio with the sum of squares over the whole time seriesx. Linear trend of x Computes a linear least-squares regression for thevalues of the time series x versus the sequence from 0 to length of thetime series x minus one. Maximum(x) Computes the highest value of thetime series x Minimum(x) Computes the lowest value of the time series x${f(x)} = \{ \begin{matrix}{{1\mspace{14mu}{if}\mspace{14mu}{{{\sum\limits_{i}x_{i}} - {me{d(x)}}}}} < {\alpha( {{\max(x)} - {\min(x)}} )}} \\{0\mspace{14mu}{otherwise}}\end{matrix} $ Symmetry test of time series x that returns 1 if apercent α of the distribution of time series x looks symmetric and 0otherwise

In addition (or in the alternative) to the data insights describedabove, in one or more embodiments, the visual-data-story system 106determines other various statistical values for the data-attributevalues organized in a time series x for a particular dataset group. Forexample, the visual-data-story system 106 determines (or calculates)statistical values such as, but not limited to, a mean, median, and/ormode of the data-attribute values organized in the time series x for theparticular dataset group. Then, in some embodiments, thevisual-data-story system 106 utilizes the determined statistical valuesas data insights for the data-attribute values organized in the timeseries x for the particular dataset group.

As shown in FIG. 4, upon determining one or more data insights for oneor more dataset groups, the visual-data-story system 106 utilizes thedata story template 408 to generate the visual data story 412. Inparticular, in one or more embodiments, the visual-data-story system 106extracts and generates the data story properties from the data storytemplate 408 and then utilizes a natural language generator (NLG) togenerate a natural language summary for the data insights determinedfrom the one or more dataset groups. As mentioned above, in reference toFIG. 4, the visual-data-story system 106 extracts data story properties,such as the data-attribute category name 410 a, the data-attributevalues 410 b, the dataset group name 410 c, and the story name 410 f forthe particular one or more dataset groups.

In addition, in one or more embodiments, the visual-data-story system106 utilizes the determined data insights as the dataset group insights410 d (from FIG. 4). Furthermore, in one or more embodiments, thevisual-data-story system 106 utilizes the determined data insights(e.g., dataset group insights 410 d) to determine insight comparisons410 e (from FIG. 4) as a data story property. For example, the insightcomparisons 410 e include the visual-data-story system 106 identifyingif the dataset group insights are similar (e.g., data insights from twodataset groups are identified as similar if they both include anincreasing trend determination). Likewise, the insight comparisons 410 einclude the visual-data-story system 106 identifying if the datasetgroup insights are different (e.g., data insights from two datasetgroups are identified as different if one data insight identifiessignificant value changes from derived data values of a first data groupwhereas another data insight does not identify significant value changesfrom derived data values of a second data group).

Furthermore, in one more embodiments, the visual-data-story system 106provides the data-attribute category name 410 a, the data-attributevalues 410 b, the dataset group name 410 c, and the story name 410 f forthe particular dataset groups with the dataset group insights 410 d andthe insight comparisons 410 e to an NLG to generate a natural languagesummary of a visual data story. For example, the visual-data-storysystem 106 utilizes the NLG to select transition words based on theinsight comparisons 410 e. To illustrate, when data insights from twodataset groups are identified as similar (e.g., both having anincreasing and/or decreasing trend determination), the visual-data-storysystem 106 selects “similarly” as a transition word between the two datainsights (through the NLG). Likewise, as an example, when data insightsfrom two dataset groups are identified as different (e.g., the twodataset groups having opposing trend determinations), thevisual-data-story system 106 selects “to contrast” or “differently” as atransition word between the two data insights (through the NLG). In oneor more embodiments, the visual-data-story system 106 utilizes variousnatural language generators including, but not limited to, Markovchain-based NLGs, recurrent neural network-based NLGs, long short-termmemory-based NLGs, and/or self-attention mechanism-based NLGs.

Having determined data story properties as part of a data storytemplate, the visual-data-story system 106 also utilizes the variousvisual data story properties to generate graphical visualizations and/oranimations for the one or more dataset groups (and the correspondingdata insights). For example, the visual-data-story system 106 structuresthe identifies visual data story properties into a graphicalvisualization structure to generate the visual data story. In one ormore embodiments, the visual-data-story system 106 inserts the variousvisual data story properties into an appropriate structure of a visualdata story template (e.g., a title, chart axes, dataset group labels) togenerate a visual data story (e.g., with a chart or graph). As part of avideo animation, the visual-data-story system 106 also includes naturallanguage summaries, data insights, and/or data insight comparisons whenthe particular natural language summaries, data insights, and/or datainsight comparison is applicable to the graphical visualization for theone or more dataset groups.

As shown in FIG. 4, in some embodiments, the visual-data-story system106 determines multiple data insights to compare two dataset groups(e.g., different dataset groups) and further generates visual datastories that reflect the multiple data insights. By contrast, in one ormore embodiments, the visual-data-story system 106 determines datainsights and generates a visual data story for a singular dataset group.Although one or more embodiments herein describe the visual-data-storysystem 106 generating visual data stories for one or two data insights(for one or two dataset groups), the visual-data-story system 106, insome instances, determines various numbers of data insights for variousnumbers of dataset groups to generate visual data stories. Furthermore,in some embodiments, the visual-data-story system 106 determines datainsights and generates visual data stories for a variety ofdata-attribute values and data-attribute categories and dataset groupswithin those data-attribute categories.

In some embodiments, the visual-data-story system 106 determines datainsights and generates visual data stories for a variety ofdata-attribute categories and dataset groups utilizing an order ofactions, as outlined in the following pseudo-code of Table 2.

TABLE 2 Procedure Timeseries_Insight_Generation(X′); while all y denotea data-attribute category where 

 is the set of k = | 

 | do   generate_visualization(X′(y));   if the percentage ofx_(i) ∈X′(y) that are higher than previous sliding   window         > thresholdpercentage then     NLG(y, x, IncreasingTrend);   else     if thepercentage ofx_(i) ∈ X′(y) that are higher than previous     slidingwindow           < threshold percentage then       NLG(y, x,DecreasingTrend);     else       determine data distribution insights;    end   end   set TimeseriesSegmentInsight = Energy Ratio by kportions over   X′(y);  generate_visualization(TimeseriesSegmentInsight);   NLG(y, x,TimeseriesSegmentInsight); end

For example, in reference to Table 2, for a dataset group X′ from adata-attribute category y, the visual-data-story system 106 firstgenerates a graphical visualization of the data-attribute values thatcorrespond to the dataset group X′(y). Then, in one or more embodiments,the visual-data-story system 106 determines whether the data-attributevalues corresponding to the dataset group X′(y) are experiencing anincreasing trend or a decreasing trend over a time series (e.g., inaccordance with one or more embodiments).

In further reference to Table 2, upon determining that thedata-attribute values corresponding to the dataset group X′(y) areexperiencing an increasing and/or decreasing trend, in some embodiments,the visual-data-story system 106 utilizes a natural language generation(e.g., NLG) to generate an increasing and/or decreasing trend summaryfor the dataset group X′(y). In some instances, if the data-attributevalues corresponding to the dataset group X′(y) is not experiencing anincreasing and/or decreasing trend, the visual-data-story system 106determines other trends (e.g., a data distribution trend as describedabove) for the dataset group X′(y).

In addition to detecting and summarizing such data trends, in someembodiments (in reference to Table 2), the visual-data-story system 106also determines a time series segment insight. More specifically, asdescribed above, in some instances, the visual-data-story system 106determines energy ratios of k portions (or segments) of thedata-attribute values corresponding to the dataset group X′(y) (e.g.,TimeseriesSegmentInsights). The visual-data-story system 106 utilizesthe energy ratios of the portions (or segments) to generate avisualization of a particular segment within the time series (e.g., asshown in FIG. 8) and also a natural language summary using the energyratios of the portions (or segments).

Although Table 2 illustrates a specific order of actions, in someembodiments, the visual-data-story system 106 determines a variety ofdata insights and generates visual data stories for a variety of datasetgroups. For example, the visual-data-story system 106 utilizes a similarorder of actions to determine other data insights (e.g., derived values,data value extremums, data value minimums) and generates visual datastories for those data insights. By doing so, in one or moreembodiments, the visual-data-story system 106 generates a number ofvisual data stories from an input dataset (e.g., the input dataset 402).

As also mentioned above, in some embodiments, the visual-data-storysystem 106 generates a visual-data-story graph. For example, FIG. 5illustrates the visual-data-story system 106 determining similaritydistances between data-story properties of visual-data-story pairs fromvisual data stories to generate a visual-data-story graph. As shown inFIG. 5, the visual-data-story system 106 identifies visual data stories502 and determines similarity distances in an act 504 for variouscombinations (e.g., visual-data-story pairs) of the visual data stories502. For example, as illustrated in FIG. 5, the visual-data-story system106 determines a variety of similarity distances 506 between data-storyproperties, which include data-attribute distances 508 a, group-namedistances 508 b, group-attribute distances 508 c, and group-insightdistances 508 d.

In particular, as shown in FIG. 5, the visual-data-story system 106utilizes various combinations of the similarity distances 506 togenerate a visual-data-story graph 510. The visual-data-story graph 510includes the visual data stories 502 as nodes that are connected byedges that represent similarity distances (d_(n)) determined betweenvarious combinations (e.g., visual-data-story pairs) of the visual datastories 502. Although FIG. 5 illustrates edges between some of the nodesof the visual data stories 502 in the visual-data-story graph 510, insome instances, the visual-data-story system 106 determines edges (assimilarity distances and/or scores) between a variety of combinations ofthe generated visual data stories within a visual-data-story graph.Although FIG. 5 illustrates the visual-data-story graph 510 havingsimilarity distances between visual data stories, in one or moreembodiments, the visual-data-story system 106 utilizes the similaritydistances to generate a similarity score between visual data stories(e.g., as described below in relation to functions 9 and 10).

As further illustrated in FIG. 5, the visual-data-story system 106selects visual data stories in an act 512 from the visual-data-storygraph 510. In particular, as shown in FIG. 5, the visual-data-storysystem 106 utilizes a threshold distance 516 with a selected story 518(e.g., an initial visual data story) to select visual data stories fromthe visual-data-story graph 510. In one or more instances, the selectedstory 518 includes a visual data story that is initially presentedwithin a graphical user interface by the visual-data-story system 106.For example, the visual-data-story system 106 displays one or moreinitial visual data stories within a graphical user interface (e.g., avisual-data-story-home panel). Indeed, in some instances, thevisual-data-story system 106 displays the initial visual data storiesbased on similarity distances within a visual-data-story graph, usersettings, and/or in relation to an overarching dataset group.

To illustrate, in some instances, the visual-data-story system 106displays an initial visual data story within a graphical user interface(e.g., the visual-data-story-home panel) by surfacing a visual datastory represented by the visual-data-story graph that belongs topairings with the lowest similarity distances (e.g., fromvisual-data-story pairs that are most similar by meeting a similaritydistance threshold). In some embodiments, the visual-data-story system106 displays an initial visual data story by filtering (e.g., asdescribed in relation to FIG. 2) and surfacing an initial visual datastory from the visual-data-story graph using a user setting indicatedfilter for a particular data-attribute category and/or dataset group(e.g., filtering visual data stories that relate to the U.S.). Moreover,in some instances, the visual-data-story system 106 displays one or moreinitial visual data stories by displaying a visual data story thatcorresponds to an overarching (or largest) dataset group (e.g.,surfacing visual data stories that correspond to the overarching datasetgroup of Global as it includes each dataset group in the data-attributecategory of Country). Indeed, in one or more embodiments, thevisual-data-story system 106 receives a selection of a visual data story(e.g., selected story 518) from one or more initial visual data storiesdisplayed within the visual-data-story-home panel graphical userinterface.

Then, the visual-data-story system 106 identifies and selects visualdata stories from the visual-data-story graph 510 that are within thethreshold distance 516 from the selected story 518 as similar stories520. Furthermore, the visual-data-story system 106 identifies andselects visual data stories from the visual-data-story graph 510 thatare more than the threshold distance 516 from the selected story 518 asdissimilar stories 522. In some cases, the visual-data-story system 106identifies and selects the dissimilar stories 522 as the visual datastories that are at least a predefined number (e.g., 1 times, 1.5 times,2 times) the threshold distance 516 away from the selected story 518. Insome embodiments, the visual-data-story system 106 utilizes the similarstories 520 and the dissimilar stories 522 as visual data storyrecommendations.

Although FIG. 5 illustrates the visual-data-story system 106 utilizingthreshold distance 516, in one or more embodiments, thevisual-data-story system 106 utilizes a threshold similarity score whenthe edges of the visual-data-story graph 510 are converted to similarityscores using the corresponding similarity distances (e.g., as describedbelow in relation to functions 9 and 10). Furthermore, in one or moreembodiments, the visual-data-story system 106 identifies (or receives) athreshold distance and/or threshold similarity score from user settings(e.g., as described in FIG. 2). Additionally, in one or moreembodiments, a similarity distance (or distance) includes one or morevalues that represent a quantification of similarity between twoelements (e.g., data insights, visual data stories, visual data storyproperties). For example, a similarity distance includes a numericalvalue (e.g., as a vector value, a real number, or a normalized value)that measures similarity in terms of space between the two elements.

As suggested above, in one or more embodiments, the visual-data-storysystem 106 utilizes a data story distance function that derivessimilarity distances between visual-data-story pairs by using variousdata-story properties of the visual-data-story pairs from the visualdata stories. In some instances, the visual-data-story system 106utilizes data-story properties, such as, but not limited to, dataattributes of a visual data story, a dataset group name of a visual datastory, grouping attribute of a visual data story, and/or a group insightof a visual data story (e.g., as shown in FIG. 4). Furthermore, in someembodiments, the visual-data-story system 106 utilizes the data storydistance function to combine various distances determined from thedata-story properties to determine a similarity distance. In addition(or in the alternative) to the data-story properties shown in FIG. 4,the visual-data-story system 106 can utilize a variety of otherdata-story properties as part of the similarity distances.

To illustrate, in one or more instances, the visual-data-story system106 determines a data-attribute distance between a pair of visual datastories. In particular, in one or more embodiments, thevisual-data-story system 106 compares the data-attribute values that arewithin the pair of visual data stories to determine a data-attributedistance between the pair of visual data stories. For example, thevisual-data-story system 106 identifies a first set of data-attributevalues S_(i) for a first visual data story i and a second set ofdata-attribute values S_(j) for a second visual data story j. Then, inone or more embodiments, the visual-data-story system 106 determines adata-attribute distance d_(da) (e.g., as an intersection distance) usingthe first set of data-attribute values S_(i) and the second set ofdata-attribute values S_(j) by comparing the data-attribute valueswithin the two sets using the following function:

d _(da)(S _(i) , S _(j))=max(|S _(i) |, |S _(j)|)−|S_(i) ∩S _(j)|  (3)

In some instances, the visual-data-story system 106 utilizes the abovementioned function (e.g., function (3)) to utilize a binary encoding torepresent data-attribute values of a dataset as a vector in which eachvisual data story has a vector (e.g., set of data-attribute values) thathas a value of 1 when the data-attribute value is utilized in thedataset group associated with the visual data story vector (and a valueof 0 otherwise).

As an example, the visual-data-story system 106 determines that thefirst set of data-attribute values S_(i) includes data-attribute valuesA and B (e.g., S_(i)={A, B}) and that the second set of data-attributevalues S_(j) includes data-attribute values B and C (e.g., S_(j)={B,C}). Then, the visual-data-story system 106 determines a data-attributedistance d_(da)(S_(i), S_(j)) of 2 between the visual data stories i andj when S_(i)={A, B} and S_(j)={B, C}.

Furthermore, in some embodiments, the visual-data-story system 106determines a group-name distance (e.g., a group name difference) betweena pair of visual data stories. In particular, in some embodiments, thevisual-data-story system 106 determines a distance between the datasetgroup names utilized for the pair of visual data stories. For example,the visual-data-story system 106 identifies a first set of dataset groupnames (or subgroup names) N_(i) for a first visual data story i and asecond set of dataset group names (or subgroup names) N_(j) for a secondvisual data story j. Then, in one or more embodiments, thevisual-data-story system 106 determines a group-name distance d_(gn)between the first set of dataset group names N_(i) and the second set ofdataset group names N_(j) using the following function:

d _(gn)(N _(i) , N _(j))=max(|N _(i) |, |N _(j)|)−|N_(i) ∩N _(j)|  (4)

As an example, when N_(i)={Global, US} and N_(j)={Global, China} , thevisual-data-story system 106 determines a group-name distanced_(gn)(N_(i), N_(j)) of 1 between the visual data stories i and j. Inone or more embodiments, the visual-data-story system 106 determines agroup-name distance of 0 and adds a distance of 1 for each differenceidentified between the visual data stories i and j. In some instances,the visual-data-story system 106 utilizes a group-name distance value of2 when a group-name distance of 0 is not identified between two visualdata stories.

In addition (or in the alternative) to the above similarity distances,in one or more embodiments, the visual-data-story system 106 determinesa group-attribute distance (e.g., a group dimension distance) between apair of visual data stories. More specifically, in one or moreinstances, the visual-data-story system 106 determines a distancebetween data-attribute categories that correspond to one or more datasetgroups associated with the pair of visual data stories (e.g., attributesfrom the dataset used to select the dataset groups and/or the group ofdata-attribute values for the dataset groups). For instance, thevisual-data-story system 106 identifies a first set of group attributesY_(i) for a first visual data story i and a second set of groupattributes Y_(j) for a second visual data story j. Subsequently, thevisual-data-story system 106 determines a group-attribute distanced_(gd) (e.g., as an intersection distance) between the first set ofgroup attributes Y_(i) and the second set of group attributes Y_(j)(e.g., as vectors) using the following function:

d _(gd)(Y _(i) , Y _(j))=max(|Y _(i) |, |Y _(j)|)−|Y_(i) ∩Y _(j)|  (5)

To illustrate, in one or more embodiments, when the first set of groupattributes Y_(i)={city} and the second set of group attributesY_(j)={country}, the visual-data-story system 106 determines agroup-attribute distance d_(gd)(Y_(i), Y_(j)) of 1 between the visualdata stories i and j. In some embodiments, the visual-data-story system106 utilizes the above-mentioned function (5) for group-attributedistances d_(gd)(Y_(i), Y_(j)) to find exact matches between groupattributes. In one or more additional embodiments, the visual-data-storysystem 106 utilizes a group-attribute distance function that granularlymeasures an edit distance between actual group attributes of data visualstory pairs.

In addition (or in the alternative) to the above similarity distances,in some embodiments, the visual-data-story system 106 determines agroup-insight distance (e.g., a group insight list difference) between apair of visual data stories. In particular, in some embodiments, thevisual-data-story system 106 determines a distance between sets of groupinsights from a pair of visual data stories. For example, for a firstset of group insights I_(i) from a first visual data story i and asecond set of group insights I_(j) from a second visual data story j,the visual-data-story system 106 determines a group-insight distanced_(gi) using the following function:

d_(gi)(I _(i) , I _(j)) =max(|I _(i) |, |I _(j)|)−|I_(i) ∩I _(j)|  (6)

In some instances, the visual-data-story system 106 utilizes |I_(i)| asa cardinality of the first set of group insights I_(i) and utilizes|I_(j)| as a cardinality for the second set of group insights I_(j). Asan example, in one or more embodiments, when the first set of groupinsights I_(i)={increasing, segment 1} and the second set of groupinsights I_(j)={increasing, segment 4}, then the visual-data-storysystem 106 determines a group-insight distance d_(gi)(I_(i), I_(j)) of 1because |I_(i)|=|I_(j)|=2 and |I_(i)∩I_(j)|=1 due toI_(i)∩I_(j)={increasing}.

In one or more embodiments, the visual-data-story system 106 determinesa group-insight distance of 0 and adds a distance of 1 for eachdifference identified between the visual data stories i and j. In someinstances, the visual-data-story system 106 utilizes a group-insightdistance value of 2 when a group-insight distance of 0 is not identifiedbetween two visual data stories.

As mentioned above, in one or more embodiments, the visual-data-storysystem 106 utilizes a data story distance function (e.g., as describedin function (7) below) to combine data-attribute distances, group-namedistances, group-attribute distances, and group-insight distancesdetermined from the data-story properties (as described above infunctions (3)-(6)) to determine a type of aggregate similarity distance.In particular, in one or more embodiments, the visual-data-story system106 determines an aggregate pairwise distance between visual datastories as the similarity distance between the visual data stories. Forexample, the visual-data-story system 106 combines (e.g., using a linearcombination) the determined (or computed) data-attribute distance,group-name distance, group-attribute distance, and group-insightdistance (determined as described above in functions (3)-(6)) to obtainan overall distance (or similarity distance) between the visual datastory pairing. Then, in some embodiments, the visual-data-story system106 normalizes the overall distance along a [0,1] scale to obtain afinal similarity distance for the visual data story pairing.

To illustrate, in one or more embodiments, the visual-data-story system106 utilizes a set

of n automatically generated visual data stories. Then, in someembodiments, given a set D of data story distance functions (e.g.,D={d_(da), d_(gd), d_(gn), d_(gi)} to represent the data-attributedistances, the group-attribute distances, the group-name distances, andthe group-insight distances as described above in functions (3)-(6)),the visual-data-story system 106 determines similarity distances D(i,j)between pairs of visual data stories i and j (e.g., as aggregatepairwise distances) using the following function:

$\begin{matrix}{{{D( {i,j} )} = {\sum\limits_{d \in D}{d( {i,j} )}}},{\forall i},{j = {{d_{da}( {i,j} )} + {d_{gd}( {i,j} )} + {d_{gn}( {i,j} )} + {d_{gi}( {i,j} )}}},{\forall i},j} & (7)\end{matrix}$

Furthermore, in one or more embodiments, the visual-data-story system106 normalizes the aggregate pairwise distances between pairs of visualdata stories i and j. In particular, in some embodiments, thevisual-data-story system 106 normalizes a pairwise visual data storydistance matrix D∈

^(n×n)→

^(n×n) (e.g. a distance matrix having the similarity distances D (i, j)as described above in function (7)) by scaling values of the distancematrix to be between [0, 1] using a normalization function. For example,the visual-data-story system 106 utilizes the following normalizationfunction:

g:

^(n×n)→

^(n×n) such that 0≤D _(ij) ≤, ∀i, j   (8)

Indeed, in the above normalization function, in one or more embodiments,g represents a min-max scaling function that maps the maximum D(i, j)from the distance matrix D (e.g., max(D)) to 1 and the minimum D(i, j)from the distance matrix D (e.g., min(D)) to 0. By doing so, thevisual-data-story system 106 generates distances D(i, j) between pairsof visual data stories i, j that are normalized to be between [0,1].Indeed, in one or more embodiments, the visual-data-story system 106utilizes the (non-normalized and/or normalized) distances D(i, j) (e.g.,from functions (7) and/or (8)) as the similarity distances in avisual-data-story graph.

In certain instances, the visual-data-story system 106 furtherdetermines a similarity score between visual data story pairs from asimilarity distance (e.g., various similarity distances as describedabove in relation to functions (3)-(8)). In particular, in one or moreembodiments, the visual-data-story system 106 utilizes similaritydistances (e.g., as described above in relation to functions (3)-(8)) togenerate a visual data story similarity score matrix S∈

^(n×n) in accordance with the following function:

S=(1−D _(ij) , ∀i, j∈[n]  (9)

Indeed, in one or more embodiments, the visual data story similarityscore matrix S includes similarity scores S_(ij) that correspond to apair of visual data stories i and j. For example, the visual-data-storysystem 106 determines the similarity scores S_(ij) utilizing similaritydistances D_(ij) using the following function:

S _(ij)=1−D _(ij)   (10)

In one or more embodiments, the visual-data-story system 106 identifieslarger values of the similarity scores S_(ij) as indicating a greatersimilarity between a pair of visual data stories i and j. Indeed, incertain instances, the visual-data-story system 106 utilizes similarityscores S_(ij) that increase in value as similarity distances decreaseand decrease in value when similarity distances increase for a pair ofvisual data stories. In some embodiments, the visual-data-story system106 utilizes the similarity scores S_(ij) as presentable indicators, tousers on a graphical user interface, of the similarity of a visual datastory and/or to determine whether to create an edge between nodes of thevisual data stories (in a visual-data-story graph). For example, in somecases, when the similarity score S_(ij) is non-positive (e.g.,S_(ij)≤0), the visual-data-story system 106 does not create an edgebetween the nodes of the visual data stories i and j within avisual-data-story graph.

As shown in FIG. 5, upon determining the similarity distances in the act504 (e.g., in accordance with functions (3)-(10) above), thevisual-data-story system 106 generates the visual-data-story graph 510.Indeed, as mentioned above, in some instances, the visual-data-storysystem 106 generates a visual-data-story graph that includes visual datastories as nodes that are connected by edges that represent similaritydistances (and/or scores) between the visual data story nodes. Forinstance, the visual-data-story system 106 generates a visual-data-storygraph G=(V, E, S), where V constitutes the nodes representingauto-generated visual data stories, E constitutes the set of edgesrepresenting pairwise similarities between visual data stories, and Sconstitutes the visual data story similarity score matrix based onsimilarity distances(e.g., as described above in relation to functions 9and 10).

In some embodiments, the visual-data-story system 106 includes an edgein the set E for positive pairwise similarities between visual datastories. For instance, the visual-data-story system 106 includes an edge(i, e)∈E with weight between visual data story i and visual data story jif a similarity score S_(ij) (e.g., as described in relation tofunctions (9) and (10)) is positive (e.g., S_(ij)>0). Accordingly, insome embodiments, the visual-data-story system 106 does not generate arelationship (e.g., an edge) in the visual-data-story graph G for a pairof visual data stories from the set of visual data stories S with asimilarity score of 0 (e.g., min(S)=0). Indeed, in one or moreinstances, the visual-data-story system 106 defines the set of edges Esuch that Ē=

×

\E or Ē∪E=

×

. Although one or more embodiments illustrate edges of thevisual-data-story graph having similarity scores, in some cases, thevisual-data-story system 106 utilizes any combination of similaritydistances (e.g., as described in relation to functions (3)-(8)) for theedges of the visual-data-story graph.

As mentioned above, in one or more embodiments, the visual-data-storysystem 106 provides selectable options to select (e.g., bookmark) visualdata stories and to combine (e.g., stitch) the selected visual datastories. For example, FIG. 6 illustrates the visual-data-story system106 combining selected visual data stories into a larger, coherentvisual data story. As shown in FIG. 6, the visual-data-story system 106provides, for display within a graphical user interface of a clientdevice 602, a selectable option 604 to bookmark (or select) a visualdata story. In particular, as shown in FIG. 6, upon receiving anindication of a user interaction with the selectable option 604, thevisual-data-story system 106 includes the selected visual data story(e.g., the visual data story corresponding to the selectable option 604)within bookmarked stories 606.

Indeed, the visual-data-story system 106, as shown in FIG. 6, generatesa set of bookmarked-visual-data stories (e.g., story 1, story 5, story10, and story 15) as the bookmarked stories 606 upon receiving anindication of user interactions with selectable options to bookmark (orselect) the visual data stories within the bookmarked stories 606. Inone or more embodiments, the visual-data-story system 106 receivesrequests to bookmark a variety of visual data stories. Moreover, in someembodiments, the visual-data-story system 106 provides, for displaywithin a graphical user interface, a selectable option to bookmark avisual data story within each visual data story.

Furthermore, as illustrated in FIG. 6, the visual-data-story system 106also combines visual data stories in an act 608. For example, thevisual-data-story system 106 receives an indication of a user selection(from the client device 602) to combine (or stitch) the set ofbookmarked-visual-data stories (from the bookmarked stories 606). Insome instances, the visual-data-story system 106 provides, for displaywithin the graphical user interface of the client device 602, aselectable option to stitch (or combine) bookmarked (or selected) visualdata stories. As shown in FIG. 6, upon receiving a request to stitch thebookmarked-visual-data stories, the visual-data-story system 106combines visual data stories from the bookmarked stories 606 in the act608 to generate a stitched-visual-data story 610 (e.g., a larger,coherent visual data story). For example, as shown in FIG. 6, thestitched-visual-data story 610 generated from stitching bookmarkedstories 606 results in a visual data story that represents multiple datainsights as a presentable report that is exportable to a preferred fileformat (e.g., on the client device 602).

In some embodiments, the visual-data-story system 106 combines (orstitches) bookmarked (or selected) visual data stories such that thevisual data stories transition naturally and avoid overlapping datainsights. For example, the visual-data-story system 106 combines visualdata stories by utilizing a similarity distance (or similarity score)between each pairing of the bookmarked-visual-data stories to determinean order of the bookmarked-visual-data stories. Then, in certaininstances, the visual-data-story system 106 utilizes the determinedorder to combine the bookmarked visual data stories into astitched-visual-data story (e.g., a single coherent visual data story)that represents the data insights illustrated within the set ofbookmarked-visual-data stories.

Furthermore, in one or more embodiments, the visual-data-story system106 utilizes a minimum spanning tree algorithm to combine (or stitch)bookmarked-visual-data stories to generate a stitched-visual-data story.For example, the visual-data-story system 106 generates avisual-data-story subgraph having a set of edges that exist betweennodes of the set of bookmarked-visual-data stories. Then, in someembodiments, the visual-data-story system 106 identifies a minimumspanning tree that connects the nodes of the set ofbookmarked-visual-data stories and utilizes the minimum spanning tree tosequence the bookmarked-visual-data stories in an order determined bytraversing the minimum spanning tree of the nodes of the set ofbookmarked-visual-data stories in the visual-data-story subgraph.Indeed, in some instances, the visual-data-story system 106 utilizes thesequenced order of the bookmarked-visual-data stories to generate thestitched-visual-data story.

To illustrate, in certain instances, the visual-data-story system 106utilizes a subset of bookmarked-visual-data stories W from the set ofvisual data story nodes V from the visual-data-story graph G (e.g., W⊆V)to generate, from the visual-data-story graph G, a visual-data-storysubgraph H=(W, E[W]) that includes a subset of edges E[W] from the setof edges E that exist between the nodes corresponding to the subset ofbookmarked-visual-data stories W (e.g., E[W]⊆E). Then, in someembodiments, from the visual-data-story subgraph H, thevisual-data-story system 106 identifies a minimum spanning tree T thatconnects the subset of bookmarked-visual-data stories W. In certaininstances, the visual-data-story system 106 traverses the minimumspanning tree T using a depth-first-search and/or short branch firstapproach to determine a sequence of order for the bookmarked-visual-datastories (e.g., to generate the stitched-visual-data story).

For example, the visual-data-story system 106 utilizes a firstbookmarked visual data story as a root node of the minimum spanning treeT and utilizes the depth-first-search and/or a short branch firstapproach to generate a sequence of visual data stories beginning fromthe root node. Then, in one or more embodiments, the visual-data-storysystem 106 utilizes the sequence of visual data stories to generate astitched-visual-data story that follows the sequence. In some instances,the visual-data-story system 106 receives a selection (or reselection)of a root node for the stitched-visual-data story and generates (orregenerates) the sequence of the bookmarked-visual-data stories based ondetermining a minimum spanning tree based on the new root node.

To illustrate, in one or more embodiments, upon identifying fivebookmarked-visual-data stories (e.g., Global vs. U.S., U.S. vs. Brazil,U.S. vs. China, China vs. Italy, and China vs. Australia), thevisual-data-story system 106 generates a visual-data-story subgraph andsimilarity distances of edges between pairs of the fivebookmarked-visual-data stories as shown in Table 3 below.

TABLE 3 Global vs. U.S. vs. U.S. vs. China vs. China vs. U.S. BrazilChina Italy Australia Global vs. U.S. INFIN- 2 3 4 3 ITY U.S. vs. Brazil2 INFIN- 2 4 3 ITY U.S. vs. China 3 2 INFIN- 4 4 ITY China vs. Italy 4 44 INFIN- 2 ITY China vs. 3 3 4 2 INFIN- Australia ITY

Then, in one or more embodiments, the visual-data-story system 106generates a minimum spanning tree for the above-mentioned fivebookmarked-visual-data stories in which the Global vs. U.S. visual datastory includes two branches (e.g., one branch for the U.S. vs. Brazilvisual data story and one branch for the China vs. Australia visual datastory), the U.S. vs. Brazil visual data story further branches to theU.S. vs. China visual data story, and the China vs. Australia visualdata story further branches to the China vs. Italy visual data story.Moreover, in one or more embodiments, the visual-data-story system 106utilizes the above-mentioned minimum spanning tree for the fivebookmarked-visual-data stories to generate a visual-data-story thatfollows the minimum spanning tree order.

In one or more embodiments, the visual-data-story system 106 alsoprovides one or more transitions (and removes overlapped data insights)from the above mentioned five bookmarked-visual-data stories (aftergenerating the ordered minimum spanning tree) to generate the followingnatural language summary:

The number of number of COVID-19 confirmed cases for Global isincreasing. In detail, dividing the time series into 4 time segments,the number of COVID-19 confirmed cases for Global increases the fastestin the time segment 4. Similarly, the number of COVID-19 confirmed casesfor the U.S. is increasing. And dividing the time series into 4 timesegments, the number of COVID-19 confirmed cases for the U.S. increasesthe fastest in the time segment 4. The comparison between the U.S. andBrazil is similar. The number of COVID-19 confirmed cases for Brazil isincreasing. And dividing the time series into 4 time segments, thenumber of COVID-19 confirmed cases for Brazil increases the fastest inthe time segment 4. However, the comparison between the U.S. and Chinais different. Although the number of COVID-19 confirmed cases for Chinais increasing. But dividing the time series into 4 time segments, thenumber of COVID-19 confirmed cases for China increases the fastest inthe time segment 1. Compared to the comparison between Global and theU.S., the comparison between China and Australia is a different story.The number of COVID-19 confirmed cases for China is increasing. Indetail, dividing the time series into 4 time segments, the number ofCOVID-19 confirmed cases for China increases the fastest in the timesegment 1. Although the number of COVID-19 confirmed cases for Australiais increasing. But dividing the time series into 4 time segments, thenumber of COVID-19 confirmed cases for Australia increases the fastestin the time segment 4. The comparison between China and Italy is alsodifferent. Although the number of COVID-19 confirmed cases for Italy isincreasing. But dividing the time series into 4 time segments, thenumber of COVID-19 confirmed cases for Italy increases the fastest inthe time segment 2.

Furthermore, in one or more embodiments, the visual-data-story system106 provides options, within a graphical user interface, to modify astitched-visual-data story. For example, the visual-data-story system106 provides interactive options, within a graphical user interface, tomodify the visual appearance of the stitched-visual-data story (or avisual data story). In some instances, the visual-data-story system 106provides interactive options, within a graphical user interface, toreorganize visual data stories within the stitched-visual-data story toreorganize the order and/or placement of the visual data stories. Inaddition, in one or more embodiments, the visual-data-story system 106provides interactive options, within a graphical user interface, tomodify content (e.g., text and/or visual) of visual data stories orvisual data story natural language summaries. Moreover, as describedabove in relation to FIG. 2, the visual-data-story system 106 generates(or outputs) the finalized stitched-visual-data story as an exportablefile in various formats within a graphical user interface, video (e.g.,a video file), website, and/or other digital content (e.g., a PDF,infographic posters, or another exportable file).

In one or more embodiments, the visual-data-story system 106 is hostedon server device(s) and interacts with a client device to generate avisual data story (or a stitched-visual-data story). For example, FIG. 7illustrates a front-end client device and back end server device flow ofthe visual-data-story system 106 generating a visual data story inaccordance with one or more embodiments. As shown in FIG. 7, thevisual-data-story system 106 receives an input dataset 702 on the clientdevice 110 which is sent to the server device(s) 102. Then, as shown inFIG. 7, the visual-data-story system 106 utilizes the dataset forautomatic data insight generation in an act 704. Furthermore, as shownin FIG. 7, the visual-data-story system 106 utilizes the generated (ordetermined) data insights from the input datasets to generate visualdata stories with the extracted data insights in an act 706.

As further illustrated in FIG. 7, the visual-data-story system 106utilizes the visual data stories to determine a pairwise distance (e.g.,similarity distances) between the generated visual data stories in theact 708. Indeed, as further shown in FIG. 7, the similarity distancesare utilized to generate a visual-data-story graph in the act 710.Additionally, the visual-data-story system 106 provides thevisual-data-story graph to the client device 110. By providing such agraph, the visual-data-story system 106 provides a map or guide for theclient device 110 to navigate visual data stories based on thevisual-data-story graph. Accordingly, before or as part of suchnavigation, the visual-data-story system 106 data for the underlyingvisual data stories for display on the client device 110.

Indeed, FIG. 8A illustrates the visual-data-story system 106 providing,for display within a graphical user interface 804 of a client device802, a visual data story 806. As further illustrated in FIG. 8A, withina movie view, the visual-data-story system 106 provides, for displaywithin the graphical user interface 804, the visual data story 806 as ananimated video that plays upon detecting a user interaction with theselectable option 808. Based on detecting a selection of the selectableoption 808, the client device 802 displays a video depicting changingdata as part of a time series as the first graphical visualization 811changes over time. Indeed, in one or more embodiments, thevisual-data-story system 106 provides, for display within the graphicaluser interface 804, a video of the visual data story 806 with a firstgraphical visualization 811 and a first natural language summary 812. Insome instances, the visual-data-story system 106 also generates an audiooutput of the first natural language summary 812 from the client device802.

As illustrated in FIG. 8B and as a progression of the video of thevisual data story 806 from the illustration of FIG. 8A, thevisual-data-story system 106 displays, within the graphical userinterface 804 of the client device 802, a second graphical visualization814 (e.g., displaying both Global Total Cases and Global Daily Cases)and a second natural language summary 816 as part of the visual datastory 806. In certain instances, the visual-data-story system 106 alsogenerates an audio output of the second natural language summary 816from the client device 802.

As further shown in FIG. 8B, the visual-data-story system 106 provides,for display within the graphical user interface 804, a highlightedportion 815 associated with a segment (e.g., a time segment) of thevisual data story 806. Indeed, as illustrated in FIG. 8B, thevisual-data-story system 106 includes the highlighted portion 815 withinsecond graphical visualization 814 to indicate (or emphasize) a specificdata insight corresponding to the segment (e.g., the time segment) fromthe visual data story 806. As shown in FIG. 8B, the visual-data-storysystem 106 utilizes the highlighted portion 815 to indicate the datainsight within the second natural language summary 816 (e.g., within atime segment 4).

As a further progression of the video of the visual data story 806 fromthe illustration of FIG. 8B, FIG. 8C illustrates the visual-data-storysystem 106 displaying, within the graphical user interface 804 of theclient device 802, a third graphical visualization 818 and a thirdnatural language summary 820 as part of the visual data story 806. Insome instances, the visual-data-story system 106 also generates an audiooutput of the third natural language summary 820. Indeed, as shown inFIG. 8C, the visual-data-story system 106 displays charts for U.S. TotalCases and U.S. Daily Cases in comparison to the Total and Daily Casesfor Global within the third graphical visualization 818. As indicated bythe progression of the visual data story 806 shown in FIGS. 8A-8C, insome cases, the first natural language summary 812, the second naturallanguage summary 816, and the third natural language summary 820 eachcomprise a segment of a larger natural language summary.

As further shown in FIG. 8C, the visual-data-story system 106 alsodisplays a highlighted portion 819 within the third graphicalvisualization 818 to indicate (or emphasize) a specific data insightcorresponding to the segment (e.g., the time segment) from the visualdata story 806. Indeed, as shown in FIG. 8C, the visual-data-storysystem 106 utilizes the highlighted portion 819 to indicate the datainsight within the third natural language summary 820 (e.g., within atime segment 4).

In addition to various components of the visual data story 806, asillustrated in FIG. 8C, the visual-data-story system 106 provides, fordisplay, a selectable option 822 to bookmark (or select) the visual datastory 806. For example, in one or more embodiments, thevisual-data-story system 106 receives a user interaction with theselectable option 822 and adds the visual data story 806 within thebookmarked-visual-data stories. Indeed, the visual-data-story system 106sometimes utilizes the visual data stories that are selected with theselectable option 822 (e.g., the bookmarked-visual-data stories) togenerate a stitched-visual-data story (as described above).

In some instances, the visual-data-story system 106 also provides, fordisplay within a graphical user interface, a summary view of a visualdata story. For instance, FIG. 8D illustrates the visual-data-storysystem 106 providing, for display within the graphical user interface804 of the client device 802, a summary view of the visual data story806 (e.g., by interacting with the “view style” dropdown menu 823). Inthe summary view, the visual-data-story system 106 provides a textdescription 825 (e.g., the complete natural language summarycorresponding to the visual data story) on one portion of the graphicaluser interface 804 while displaying a graphical visualization 827corresponding to data insights on another portion of the graphical userinterface 804. In some cases, upon detecting an interaction (e.g., acursor hover and click) over a portion of the natural language summaryin the text description 825, the visual-data-story system 106 provides,for display within the graphical user interface 804, an accompanyingvisualization of the selected data insight within the visual data story806 (or the graphical visualization 827).

As indicated above, in some embodiments, the visual-data-story system106 provides, for display within a graphical user interface, a varietyof similar and/or dissimilar visual data stories as recommendations froma visual-data-story graph. For example, as shown in FIG. 8D, thevisual-data-story system 106 also provides, for display within thegraphical user interface 804, a recommended visual data stories panel824. As also shown in FIG. 8D, the visual-data-story system 106provides, for display within the graphical user interface 804, bothsimilar and dissimilar (e.g., different) visual data stories within therecommended visual data stories panel 824 that are selected using thevisual data story 806 within a visual-data-story graph (in accordancewith one or more embodiments). Indeed, as illustrated in FIG. 8D, thevisual-data-story system 106 also provides, for display within thegraphical user interface 804, selectable option 826 to select visualdata stories (e.g., for a similar and/or different visual data story)from the recommended visual data stories panel 824.

Upon receiving a user interaction with the selectable option 826 (e.g.,as a thumbnail for the Global vs. Brazil data story), thevisual-data-story system 106 changes from display of the visual datastory 806 to the content corresponding to a visual data storycorresponding to the selectable option 826. For example, based onreceiving a user interaction with the selectable option 826, thevisual-data-story system 106 displays, within the graphical userinterface 804 of the client device 802, a visual data story 831 (asillustrated in FIG. 8E). As shown in FIG. 8E, the visual-data-storysystem 106 displays, within the graphical user interface 804, agraphical visualization 828 as part of the visual data story 831 (e.g.,Global vs. Brazil visual data story). Moreover, as shown in FIG. 8E, thevisual-data-story system 106 also displays, within the graphical userinterface 804, a selectable option 834 to play the visual data story 831as an animated video (e.g., as described above). Indeed, upon detectinga selection of the selectable option 834, visual-data-story system 106displays a video depicting changing data as part of a time series as thevisual data story 831 changes over time (with natural languagesummaries, audio output of the natural language summaries, and/orhighlighted insights).

As also shown in FIG. 8E, the visual-data-story system 106 analternative collection of similar or dissimilar visual data stories fordisplay within the recommended visual data stories panel 829 based onrelationships in a visual-data-story graph. Although FIG. 8E illustratessimilar visual data stories in the recommended visual data stories panel829, in one or more embodiments, the visual-data-story system 106provides, for display within the graphical user interface 804, differentvisual data stories (as determined using a visual-data-story graph) andselectable options to select the different visual data stories. As alsoshown in FIG. 8E, the visual-data-story system 106 provides, for displaywithin the graphical user interface 804, a selectable option 830 (e.g.,selectable tab) to navigate to visual data story 806 from FIGS. 8A-8Dand a selectable option 832 (e.g., selectable tab) to navigate to thevisual data story 831.

Although not shown in FIGS. 8A-8E, in one or more embodiments, thevisual-data-story system 106 also provides, for display within agraphical user interface, a visual-data-Attorney story-home panel thatincludes one or more recommended visual data stories from avisual-data-story graph (as also mentioned in FIG. 5). In particular, inone or more embodiments, the visual-data-story system 106 provides, fordisplay within a graphical user interface, one or more auto recommendedvisual data stories as a starting point (for a user browsing visual datastories in response to uploading an input dataset). In some cases, thevisual-data-story system 106 utilizes an interest level corresponding toa visual data story to auto recommend the visual data story (e.g., basedon previous views, feedback, level of generality used in visual datastory). In certain instances, the visual-data-story system 106 utilizesa machine learning model to determine the interest levels (or rank) thevisual data stories to recommend the visual data stories.

Moreover, in one or more embodiments, the visual-data-story system 106receives user interactions from a client device to edit or modify avisual data story. For example, the visual-data-story system 106receives user interactions to modify graphical visualizations and/ornatural language summaries within a graphical user interface thatdisplays a visual data story. Upon receiving user interactions to modifyone or more graphical visualizations and/or the natural languagesummaries, the visual-data-story system 106 modifies the one or moregraphical visualizations and/or the natural language summaries. Forexample, the visual-data-story system 106 modifies one or more graphicalvisualizations and/or the natural language summaries by modifyingcolors, modifying chart styles, modifying text, and/or modifying titles.In some instances, the visual-data-story system 106 also adds and/orremoves data insights (or visual data stories) from the graphical userinterface by interacting (e.g., a double click) with the visual datastory or natural language summary.

In addition, in some embodiments, the visual-data-story system 106provides, for display within a graphical user interface, a search bar(e.g., for text input) to search through visual data stories. Forinstance, the visual-data-story system 106 receives a keyword searchthrough the search bar and utilizes the keywords to search for relevantvisual data stories from a visual-data-story graph. As an example, thevisual-data-story system 106 searches for the keywords provided via thesearch bar in the content and/or visual-data story properties of thevisual data stories in visual-data-story graph. Upon identifying one ormore visual data stories based on the keyword search, thevisual-data-story system 106, provides, for display within a graphicaluser interface, the one or more visual data stories. In one or moreembodiments, the visual-data-story system 106 provides, for displaywithin a graphical user interface, a visual data story (e.g., inaccordance with FIG. 8) upon receiving a selection of the visual datastory from the search result visual data stories.

As mentioned above, the visual-data-story system 106 provides, fordisplay, graphical user interfaces that increase the efficiency and easeof quickly reviewing and selecting visual data stories to generateexportable files for one or more visual data stories. In someembodiments, the visual-data-story system 106 also provides suchfunctionality on client devices that have small and/or limited screenspace. Indeed, in one or more embodiments, the visual-data-story system106 utilizes a computationally-guided process of automaticallygenerating presentable and coherent visual data stories that indicatein-depth data insights directly from raw input data with lessnavigational steps and less specialized skills in data analysis onmobile devices with limited screen space.

For example, FIG. 9 illustrates the visual-data-story system 106providing, for display within a graphical user interface of a mobileclient device 902, a visual data story 904 (e.g., as an animated video,with a text- and/or audio-based natural language summary, an image) inaccordance with one or more embodiments. Furthermore, as shown in FIG.9, the visual-data-story system 106 also provides, for display withinthe graphical user interface of the mobile client device 902, aselectable option 905 to select (or bookmark) a visual data story togenerate a stitched-visual-data story. In some embodiments and inreference to FIG. 9, the visual-data-story system 106 provides, fordisplay within the graphical user interface of the mobile client device902, the visual data story 904 in response to receiving an input datasetfrom the mobile client device 902.

Additionally, FIG. 10 illustrates the visual-data-story system 106providing, for display within the mobile client device 1002, arecommended visual data stories panel 1006 that provides similar anddifferent visual data stories from a visual-data-story graph in relationto a selected visual data story. Indeed, as shown in FIG. 10, thevisual-data-story system 106 enables browsing and selective capabilitiesof the visual data stories on the mobile client device 1002 to generatean exportable, stitched-visual-data story (e.g., in accordance with oneor more embodiments) directly from the limited screen space of themobile client device 1002.

As mentioned above, the visual-data-story system 106 provides anefficient and quick computationally-guided process of automaticallygenerating presentable and coherent visual data stories directly fromraw input data. To test and demonstrate the efficiency and user-friendlyfunctions of the visual-data-story system 106, researchers set upparticipants to utilize the visual-data-story system 106 to generatevisual data stories from a dataset and requested the participants totake a post-study questionnaire that included Likert-scale ratingquestions and NASA TLX questions for measuring the difficulty ofcompleting tasks within the visual-data-story system 106. Theresearchers utilized the Likert-scale rating questions to determinewhether participants found (1) the visual-data-story system 106 was easyto learn and intuitive to use, (2) the summary view, movie view, thebookmark, and recommendations of visual data stories were helpful in theparticipants' story-making process, and (3) whether the composition andtext of the visual data stories and/or a stitched-visual-data story fromdetermined data insights were sensible. The Likert-scale ratingquestions resulted in median ratings that were above 6 (e.g., strongagreement on the Likert-scale rating questions).

In addition, the researchers utilized the National Aeronautics and SpaceAdministration Task Load Index (NASA TLX) questions to determine theoverall effort required by participants to utilize thecomputationally-guided process of automatically generating generated bythe visual-data-story system 106. The Likert-scale ratings furtherresulted in a median ratings that were below 2 for the NASA TLXquestions (e.g., an indication that participants required a low effortto utilize the computationally-guided process of automaticallygenerating generated by the visual-data-story system 106).

Embodiments of the present disclosure may comprise or utilize a specialpurpose or general-purpose computer including computer hardware, suchas, for example, one or more processors and system memory, as discussedin greater detail below. Embodiments within the scope of the presentdisclosure also include physical and other computer-readable media forcarrying or storing computer-executable instructions and/or datastructures. In particular, one or more of the processes described hereinmay be implemented at least in part as instructions embodied in anon-transitory computer-readable medium and executable by one or morecomputing devices (e.g., any of the media content access devicesdescribed herein). In general, a processor (e.g., a microprocessor)receives instructions, from a non-transitory computer-Attorney readablemedium, (e.g., memory), and executes those instructions, therebyperforming one or more processes, including one or more of the processesdescribed herein.

Computer-readable media can be any available media that can be accessedby a general purpose or special purpose computer system.Computer-readable media that store computer-executable instructions arenon-transitory computer-readable storage media (devices).Computer-readable media that carry computer-executable instructions aretransmission media. Thus, by way of example, and not limitation,embodiments of the disclosure can comprise at least two distinctlydifferent kinds of computer-readable media: non-transitorycomputer-readable storage media (devices) and transmission media.

Non-transitory computer-readable storage media (devices) includes RAM,ROM, EEPROM, CD-ROM, solid state drives (“SSDs”) (e.g., based on RAM),Flash memory, phase-change memory (“PCM”), other types of memory, otheroptical disk storage, magnetic disk storage or other magnetic storagedevices, or any other medium which can be used to store desired programcode means in the form of computer-executable instructions or datastructures and which can be accessed by a general purpose or specialpurpose computer.

A “network” is defined as one or more data links that enable thetransport of electronic data between computer systems and/or modulesand/or other electronic devices. When information is transferred orprovided over a network or another communications connection (eitherhardwired, wireless, or a combination of hardwired or wireless) to acomputer, the computer properly views the connection as a transmissionmedium. Transmissions media can include a network and/or data linkswhich can be used to carry desired program code means in the form ofcomputer-executable instructions or data structures and which can beaccessed by a general purpose or special purpose computer. Combinationsof the above should also be included within the scope ofcomputer-readable media.

Further, upon reaching various computer system components, program codemeans in the form of computer-executable instructions or data structurescan be transferred automatically from transmission media tonon-transitory computer-readable storage media (devices) (or viceversa). For example, computer-executable instructions or data structuresreceived over a network or data link can be buffered in RAM within anetwork interface module (e.g., a “NIC”), and then eventuallytransferred to computer system RAM and/or to less volatile computerstorage media (devices) at a computer system. Thus, it should beunderstood that non-transitory computer-readable storage media (devices)can be included in computer system components that also (or evenprimarily) utilize transmission media.

Computer-executable instructions comprise, for example, instructions anddata which, when executed by a processor, cause a general-purposecomputer, special purpose computer, or special purpose processing deviceto perform a certain function or group of functions. In someembodiments, computer-executable instructions are executed by ageneral-purpose computer to turn the general-purpose computer into aspecial purpose computer implementing elements of the disclosure. Thecomputer-executable instructions may be, for example, binaries,intermediate format instructions such as assembly language, or evensource code. Although the subject matter has been described in languagespecific to structural features and/or methodological acts, it is to beunderstood that the subject matter defined in the appended claims is notnecessarily limited to the described features or acts described above.Rather, the described features and acts are disclosed as example formsof implementing the claims.

Those skilled in the art will appreciate that the disclosure may bepracticed in network computing environments with many types of computersystem configurations, including, personal computers, desktop computers,laptop computers, message processors, hand-held devices, multi-processorsystems, microprocessor-based or programmable consumer electronics,network PCs, minicomputers, mainframe computers, mobile telephones,PDAs, tablets, pagers, routers, switches, and the like. The disclosuremay also be practiced in distributed system environments where local andremote computer systems, which are linked (either by hardwired datalinks, wireless data links, or by a combination of hardwired andwireless data links) through a network, both perform tasks. In adistributed system environment, program modules may be located in bothlocal and remote memory storage devices.

Embodiments of the present disclosure can also be implemented in cloudcomputing environments. As used herein, the term “cloud computing”refers to a model for enabling on-demand network access to a shared poolof configurable computing resources. For example, cloud computing can beemployed in the marketplace to offer ubiquitous and convenient on-demandaccess to the shared pool of configurable computing resources. Theshared pool of configurable computing resources can be rapidlyprovisioned via virtualization and released with low management effortor service provider interaction, and then scaled accordingly.

A cloud-computing model can be composed of various characteristics suchas, for example, on-demand self-service, broad network access, resourcepooling, rapid elasticity, measured service, and so forth. Acloud-computing model can also expose various service models, such as,for example, Software as a Service (“SaaS”), Platform as a Service(“PaaS”), and Infrastructure as a Service (“IaaS”). A cloud-computingmodel can also be deployed using different deployment models such asprivate cloud, community cloud, public cloud, hybrid cloud, and soforth. In addition, as used herein, the term “cloud-computingenvironment” refers to an environment in which cloud computing isemployed.
